A Guide to Pool Chemical Maintenance: Testing, Balancing, Sanitizing, and Shocking

Owning a pool is a delightful luxury, providing countless hours of fun and relaxation. However, maintaining crystal-clear water requires regular attention and care. In this blog post, we'll discuss a step-by-step guide to ensure your pool stays in pristine condition. Our focus will be on four key steps: testing the water weekly, balancing its chemical composition, adding sanitizer, and shocking the pool regularly.


  1. Test The Water Weekly: Testing the water is the first and most crucial step in maintaining a healthy pool. Using test strips or a liquid test kit, check pH, alkalinity, and sanitizer levels. These parameters directly impact water clarity and bather comfort. Regular testing catches imbalances early on, preventing larger issues down the line.

  • pH: Aim for a pH level between 7.4 and 7.6. Use pH increasers or decreasers as necessary to bring the levels into the ideal range.

  • Alkalinity: Adjust the alkalinity using an alkalinity increaser (usually baking soda). Proper alkalinity levels (80-120 ppm) stabilize the pH and prevent rapid fluctuations.

  • Sanitizer Levels: Ensure that sanitizer levels (chlorine or bromine) are within the recommended range. Adjust accordingly using the appropriate products.

  1. Balance The Water: After testing and adjusting alkalinity, retest the water to confirm pH levels. If needed, use pH increasers or decreasers to bring it into the desired range. Properly balanced water ensures bather comfort and protects pool equipment and surfaces from damage.

  2. Add Sanitizer Weekly: Maintaining a consistent sanitizer level is crucial for preventing algae growth and eliminating harmful bacteria. Depending on the type of sanitizer used (chlorine or bromine), follow the manufacturer's guidelines to determine the appropriate amount to add weekly. Regular sanitization is key to keeping your pool water safe and clear.

  3. Shock Every 1-2 Weeks: Even with regular sanitization, contaminants can build up in the water. Periodically shocking the pool breaks down organic matter, eliminate chloramines, and prevent algae growth. Follow the recommended dosage of the shock treatment product, and perform this task at night to allow the chemicals to work without sunlight interference. Run the pool pump at least 8 hours after shock to ensure proper circulation.


Regular and proactive pool maintenance is the key to enjoying clear, inviting water throughout the swimming season. By following these four essential steps – testing the water weekly, balancing its chemical composition, adding sanitizer, and shocking the pool – you'll ensure a healthy and enjoyable swimming experience for yourself and your guests. Take the time to invest in your pool's well-being, and you'll reap the benefits of a sparkling oasis all season long.
